New Solenoid Valve ASCO Valve and Fish-er 1808/1098 Pressure Reducing Regulators

The Fisher 1098-EGR (and 1098H-EGR variant) serves as a pilot-operated pressure reducing regulator, delivering economical yet highly accurate downstream pressure management. Its design uses a two-path control system where the pilot amplifies small changes for fast, stable response. This makes it a solid pick for setups needing consistent performance across varying conditions.

• Handles low differential pressures down to 1 psid / 70 mbar d with accurate control.
• Maintains stable outlet pressure even when load or inlet pressure shifts.
• Whisper Trim™ cage option cuts noise by up to 30 dBa for quieter operation.
• Top-entry design allows trim inspection, cleaning, or replacement without pulling the body from the line.
• No atmospheric bleed—pilot system sends all bleed gas downstream.
• High turn-down capability thanks to oversized diaphragm and linear cage, ideal for big flow swings.
• Bubble-tight shutoff from knife-edged metal plug and soft seat, great for dead-end systems.
• Travel indicator helps with in-service checks and troubleshooting.

Body Sizes: NPS 1, 2, 3, 4, 6, 8 x 6, 12 x 6 / DN 25, 50, 80, 100, 150, 200 x 150, 300 x 150. End Connections: NPT, CL150 RF, CL300 RF, CL600 RF, CL125FF, CL250RF, BWE, SWE, or PN 16/24/40. Maximum Inlet Pressure: 400 psig / 28 bar or body rating limit, whichever is lower. Temperature Capabilities:

• Nitrile (NBR): -20° to 180°F / -29° to 82°C
• Fluorocarbon (FKM): 0° to 300°F / -18° to 149°C
• Ethylenepropylene (EPR): -20° to 275°F / -29° to 135°C

Well-suited for natural gas distribution networks, fuel gas lines feeding industrial boilers, furnaces, ovens, and mixers, plus larger commercial or industrial sites like shopping centers and schools. It also works in plant air service and certain liquid applications.

Q: How low can the differential pressure go? A: It controls accurately at differentials as low as 1 psid / 70 mbar d.

Q: Does it bleed gas to the atmosphere? A: No—the pilot-operated setup directs all bleed back to the downstream side.

Q: Is maintenance straightforward? A: Yes, top-entry access lets you handle trim without removing the regulator from the pipeline.

Q: What about noise in high-flow setups? A: The optional Whisper Trim cage can reduce noise levels by up to 30 dBa.

Q: Can it handle dead-end systems? A: Absolutely, with its tight shutoff design for positive closure.
